Item Access Across America: Transit 2014(Center for Transportation Studies, University of Minnesota, 2014-09) Owen, Andrew; Levinson, DavidAccessibility is the ease of reaching valued destinations. It can be measured for various transportation modes, to different types of destinations, and at different times of day. There are a variety of ways to define accessibility, but the number of destinations reachable within a given travel time is the most comprehensible and transparent, as well as the most directly comparable across cities. This report examines accessibility to jobs by transit in 46 of the 50 largest (by population) metropolitan areas in the United States. Transit is used for an estimated 5 percent of commuting trips in the United States, making it the second most widely used commute mode after driving. This report complements Access Across America: Auto 2013, a report of job accessibility by auto in 51 metropolitan areas. A separate publication, Access Across America: Transit 2014 Methodology, describes the data and methodology used in this evaluation. Rankings are determined by a weighted average of accessibility, giving a higher weight to closer jobs. Jobs reachable within ten minutes are weighted most heavily, and jobs are given decreasing weight as travel time increases up to 60 minutes.Item Access Across America: Transit 2014 Data(2014-12-05) Owen, Andrew; Levinson, David M; aowen@umn.edu; Owen, Andrew; University of Minnesota Center for Transportation Studies, Accessibility ObservatoryThis data was created as part of a study that examined the accessibility to jobs by transit in 46 of the 50 largest (by population) metropolitan areas in the United States. It is the most detailed evaluation to date of access to jobs by transit, and it allows for a direct comparison of the transit accessibility performance of America's largest metropolitan areas.Item Access Across America: Transit 2014 Methodology(Center for Transportation Studies, University of Minnesota, 2014-09) Owen, Andrew; Levinson, David M.Accessibility is the ease of reaching valued destinations.

It can be measured across different times of day (accessibility in the morning rush might be lower than the less-congested midday period). It can be measured for each mode (accessibility by walking is usually lower than accessibility by transit, which is usually lower than accessibility by car). There are a variety of ways to measure accessibility, but the number of destinations reachable within a given travel time is the most comprehensible and transparent as well as the most directly comparable across cities.

It can be measured for a wide array of transportation modes, to different types of destinations, and at different times of day. There are a variety of ways to measure accessibility, but the number of destinations reachable within a given travel time is the most comprehensible and transparent as well as the most directly comparable across cities. This study estimates the accessibility to jobs by transit and walking for each of the United States’ 11 million census blocks, and analyzes these data in 49 of the 50 largest (by population) metropolitan areas. Transit is used for an estimated 5 percent of commuting trips in the United States, making it the second most widely used commute mode after driving. Travel times by transit are calculated using detailed pedestrian networks and full transit schedules for the 7:00 – 9:00 a.m. period. The calculations include all components of a transit journey, including “last-mile” access and egress walking segments and transfers, and account for minute-by-minute variations in service frequency. This report presents detailed accessibility values for each metropolitan area, as well as block-level maps that illustrate the spatial patterns of accessibility within each area.

A separate publication, Access Across America: Transit 2017 Methodology, describes the data and methodology used in this evaluation. This analysis uses the same tools and techniques as Access Across America: Transit 2015 and 2016, and at the same fully national scale; availability of GTFS data has increased in consistency. For these reasons, direct comparisons between transit accessibility results of 2015 and 2016 are possible, and comparisons and time-series analysis are included in these reports going forward.Item Access Across America: Transit 2017 Data(2018-10-08) Owen, Andrew; Murphy, Brendan; aowen@umn.edu; Owen, Andrew; University of Minnesota Center for Transportation Studies, Accessibility ObservatoryThese data were created as part of a study that examined the accessibility to jobs by transit in 49 of the 50 largest (by population) metropolitan areas in the United States.

A separate publication, Access Across America: Transit 2018 Methodology, describes the data and methodology used in this evaluation. This analysis uses the same tools and techniques as previous reports in the Access Across America: Transit series. However, beginning in data year 2018, federal jobs and federal workers are not included due to changes in underlying datasets from the U.S. Census Bureau. As a result, comparisons between 2017 and 2018 accessibility results are less accurate in areas where federal employment is a greater share of total employment.Item Access Across America: Transit 2018 Data(2020-01-31) Owen, Andrew; Murphy, Brendan; aowen@umn.edu; Owen, Andrew; University of Minnesota Center for Transportation Studies, Accessibility ObservatoryThese data were created as part of a study that examined the accessibility to jobs by transit in the 50 largest (by population) metropolitan areas in the United States.

Year-over-year changes in transit accessibility are provided for each area. The 2021 reporting year reflects the first travel year after the onset of the COVID-19 pandemic; thus the changes in accessibility include impacts of altered transit service in response to changes in travel behavior, especially reductions in office commutes due to telework.
